Commit 1a97382 introduced the fallible GUI::Application::create() and
removed GUI::Application::construct() breaking the SDL2 port, let's
update it to use the fallible version.
<Ctrl-Del> will crash when deleting at the end of line
where the next line contains only punctuation and seperator characters,
because TextDocument::first_word_break_after will return a wrong index
of the next word break (+1 bigger than the correct index),
thus RemoveTextCommand will try to remove a out-of-bound text range
causing a crash.
<Ctrl-Backspace> will stuck when deleting at the end of line
which contains only one single character. When finding the
previous word break position starting at column 0 in
TextDocument::first_word_break_before, the code enters an
infinite while loop. The early return should simply fix this.
The pattern to construct `Application` was to use the `try_create`
method from the `C_OBJECT` macro. While being safe from an OOM
perspective, this method doesn't propagate errors from the constructor.
This patch make `Application` use the `C_OBJECT_ABSTRACT` and manually
define a `create` method that can bubble up errors from the
construction stage.
This commit also removes the ability to use `argc` and `argv` to
create an `Application`, only `Main`'s `Arguments` can be used.
From a user point of view, the patch renames `try_create` => `create`,
hence the huge number of modified files.
The font isn't set in the constructor, there may be a case where the
font hasn't loaded before the first paint event. Therefore, we should
not paint if the font is null. All other methods should be fine.
`m_original_font` is only set if `GlyphMapWidget::set_font` is called.
But, if the user of `GlyphMapWidget` decides not to set a font,
there will be no value for `m_original_font`.
This commit fixes that issue by checking if `m_original_font` is not
null before attempting to use it.
We now load SVG icons (via the Qt resource system) and render them into
a QIcon (with normal and disabled variants) using system colors.
We also re-render them if the system color theme changes.
This instantly makes Ladybird look less foreign on my Linux box.
I drew the icons myself, and they could definitely be more optimized,
but this was my first time using Inkscape. :^)
The graphics directory is a more suitable home for game assets.
Also, move card backs into their own subfolder in preparation for a
themes subfolder for card fronts.
`Length::resolved(Node&)` transforms infinite values to "auto".
Following transformations:
Infinite (Length) -> "auto" -> 0 (px)
cause border-box width to be resolved in zero when it should be inf px.
Removing `Length::resolved(Node&)` makes it work right:
Infinite (Length) -> Infinite (px)
Fixes#18649
Previously we were starting the variable expansions before the starting
'$' and calculating the wrong length, this commit makes it so we
calculate the right range for them.
